| Abstract: |
| The experiment of desulfurization of sintering flue gas with pyrolusite was conducted. The results show that there are two desulfurization approaches in reaction system, i.e., mainly oxidation & reduction between MnO2 and SO2, and secondary but significant catalytic oxidation reaction of SO2. The additives added in desulfurization system can improve desulfurization rate and utilization rate of manganese resources by regulating pH of pyrolusite slurry. |
